ecoal is the country's first manufactured smokeless fuel to use 30% of its raw materials from renewable resources. These renewable materials come from plants that absorb much of the carbon dioxide that is released when solid fuel burns. This makes ecoal much kinder to the environment than other coal based smokeless fuels. ecoal, being smokeless, emits only a fifth of the smoke compared to ordinary house coal and burns efficiently with an attractive flame for longer periods.
